2. 6. Quality Assessment for the Improved Use of Recycled Styrenic Polymers : Application to packaging and electronic waste

   Author : Francisco Vilaplana; Sigbritt Karlsson; Alfonso Jimenez; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

   Abstract :  Polymeric waste materials should be considered resources for the manufacture of new products through recycling processes, with a similar status as virgin fossil-based plastics and biopolymers from renewable resources. Several efforts can be done to achieve this qualitative quantum leap and introduce recycled products in the market with competitive performance. READ MORE

4. 7. Electronic Waste Plastics Characterisation and Recycling by Melt-processing

   Author : Erik Stenvall; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melt-blending; WEEE; ternary polymer blend; processing conditions; plastics recycling; composition analysis; e-waste;

   Abstract : Melt-processing of blended plastics from waste electrical and electronic equipment (WEEE) is a method to facilitate mechanical recycling, and this might improve the recycling conditions and increase the amounts of plastics being recycled. To ensure the quality of melt-blended plastic waste, it is essential to know the composition of the incoming material and then possibly improve the compatibility between the different polymer phases.

5. 8. Reliability, fatigue and mechanical characterization of lead-free solders for electronic packaging applications

   Author : Cristina Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability.; Isothermal mechanical fatigue; Tensile tests; Mechanical behavior; Electronics; Thermal fatigue; Lead-free solders; Low cycle fatigue;

   Abstract : The ever increasing amount of electronic waste, most of which ends up in landfills, has become a serious worldwide concern. In addition to this, the fact that Pb is highly toxic and harmful to humans has lead to the ban of this element from the electronics industry. READ MORE

6. 9. Upgrading of fine residual electronic waste by microwave pyrolysis - Material Influence

   Author : Mattias Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectric properties of waste; recycling; Microwave pyrolysis; WEEE; Waste electrical and electronics equipment;

   Abstract : The large and increasing volumes of waste electrical and electronics equipment (WEEE) in society today make it important to collect and recycle these materials to as high extent as reasonable. Conventional recycling methods are based on mechanical treatments such as shredding, sorting and separation. READ MORE

7. 10. RF Energy Harvesting for Zero-Energy Devices and Reconfigurable Intelligent Surfaces

   Author : Morteza Tavana; Emil Björnson; Jens Zander; George Alexandropoulos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic waste; energy harvesting; Internet of Things; optimization; phased array; reconfigurable intelligent surfaces; stochastic geometry; wireless power transfer; wireless sensor networks; zero-energy devices.; Elektronikskrot; energiutvinning; sakernas internet; optimering; fasstyrda antenner; omkonfigurerbara intelligenta ytor; stokastisk geometri; trådlös kraftöverföring; trådlösa sensornätverk; nollenergienheter.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : The growth of Internet of Things (IoT) networks has made battery replacement in IoT devices increasingly challenging. This issue is particularly pronounced in scenarios with a large number of IoT devices, in locations where IoT devices are difficult to access, or when frequent replacement is necessary. READ MORE
